INCANDESCENT GAS-*BURNER- Application filed November 18, 1906. Serial No. 287,947.

8 is the tip of the regulator, having a pas sage for the gas and forming a valve-seat in conjunction nith the valveoint 4:. This is screw-threaded on its exterior and adapted to screw clamp the washer 7 tightly in place.

When the parts are screved together, the washer yields slightly and affords joint around the screw-threads 3, so that no gas can leak back from the interior of the regulator. This yielding frictional engagement also prevents the regulator from being .vibrated, so as to disturb its adjustment.

-9 is a burner-tube, preferably formed in one piece and having an interiorly-threaded portion adapted to the threads 2 of the base. It also has a passage 10, through which the body of the regulator may be reached for purposes of adjustment, and air-openings 11 1 adjacent to the gas-outlet.

In the form shown in screw-threads 2 for the attachment of the burner-tube are formed on the interior of an annular portion and the openings 10 for ac cess to the regulator are in the base instead of in the burner-tube. vices, however, embody of the regulatornamely, the body and tip portions and the washer.

To alt whom it may concern: I

My invention relates toiniprovements in burners for incandescent gas-light fixtures, and particularly ofthe unsen type. f

The object of the invention is to provide a simple construction which may be Inanufactured economically, adjusted readily, and which will operate efliciently without leakage of gas or variation in adjustment due to vibration.

The invention consists in improvements the principles of which are illustrated in the accompanying sheet of draa ings. Its prebase member ith' means for the admission of gas, a burnertubewith means for the admission of air, and a regulator formed in two parts and having a washer which affords frictional engagement and prevents leakage of gas.

Fig. 2 is a vertical sectional view of the same; Fig. 3 is a view sho ing the base and parts I the same elements of the regulator separated. Fig. 4 is a side view of a base and regulator of modified construction. Fig. 5 is a vertical sectional view of the same.
